MathWorld Interactive, a project by Carolynn S. Mortensen, began as MathMagic FidoNet in 1991, and was an interactive project on the Math Forum site through May 30, 1999. In June, 2002, Carolynn re-launched the project but found it necessary to close it again in November, 2002.
The interactive site was dedicated to helping educators and parents motivate their students to solve open-ended word problems, communicate mathematically, and share cultural and geographical information. Participating were students from all over the world working on open-ended word problems (levels: K-3, 4-6, 7-8, 9-12) called MathWorld Interactive Challenges. The Challenge Cycle started every 12 weeks and the students followed a specific problem-solving format.
The archived questions and submitted solutions are available.
